I would prefer to have this as a function of printing so I can still receive HTML emails.

I already tried going to Tools_Trust Center_Email Security_read all email in plain text and that didn't fix it.

I do approval of invoices all day and need to reply with forward of the original PDF document. When account receives my approval they just want to print email and pdf invoice. The problem is when they do this the header of the email doesn't show what file name was attached to the email so they can't associate the email with the pdf file unless they make notes on the email after printing.
